Fatty liver disease (fatty liver disease) is an increasingly common condition, often asymptomatic in its early stages. Many are unaware of the warning signs of this condition, which can lead to serious complications if left untreated. In this article, we’ll explore the four main signs of fatty liver disease, providing helpful information to recognize and treat them before they become problematic.

## 1. What is Fatty Liver Disease?

### 1.1 Definition

Fatty liver disease is characterized by the accumulation of fat in liver cells. It can be divided into two main categories:

– **Non-alcoholic fatty liver disease (NAFLD)**: Not related to alcohol consumption, it is often associated with obesity, diabetes, and metabolic syndrome.
– **Alcoholic fatty liver disease (AFLD)**: Caused by excessive alcohol consumption.

### 1.2 Prevalence

This condition has become one of the most common chronic diseases globally. It’s estimated that approximately 25% of the world’s population may be affected by fatty liver disease, with the incidence increasing.

## 2. The 4 Signs of Fatty Liver Disease

### 2.1 Fatigue and Tiredness

One of the most common signs of fatty liver disease is chronic fatigue. Affected individuals may feel constantly tired, even after resting.

#### Why It Happens

The liver plays a crucial role in metabolism and energy production. When this organ is overloaded with fat, its ability to metabolize nutrients and produce energy decreases, leading to a feeling of tiredness.
